I seem to have a problem processing css files with twisted.web using
twisted templates.
I get a message in my Firefox error console saying that it could not load
the css file since the type was text/html not text/css
I am running on windows 7 32bit
python 2.7.3
twisted 12.2.0
twisted templates
The template renders fine but without the styling.
I have hunted around for some ideas as to what the problem is but most seem
to be that people have not added the static file location to root.
In theory I do not have that problem since the message says it has found
the file but will not process it since it has the wrong type.
In my template file I add the link for the css file and give it the correct
file type. But I assume I have overlooked something since it refuses to
process the css.
My template is based on one of the demo templates and I have really just
added the css link
<html xmlns:t="http://twistedmatrix.com/ns/twisted.web.template/0.1">
<head>
<title>
Add Admin User
</title>
<link href="styles/jahstyle.css" rel="stylesheet" type="text/css" />
</head>
<body>
<div t:render="header" />
<ul>
<li t:render="widgets">
<t:slot name="widgetName"/>
</li>
</ul>
<div t:render="footer" />
</body>
</html>
The python that is processing this file is based on the samples I found
with some additions to add the staic file for the css
from twisted.web.server import Site, NOT_DONE_YET
from twisted.web.resource import Resource
from twisted.internet import reactor
from twisted.web import server, static
from twisted.web.template import Element, renderer, XMLFile, flattenString
from twisted.python.filepath import FilePath
class WidgetsElement(Element):
loader = XMLFile(FilePath('iteration-1.xml'))
widgetData = ['gadget', 'contraption', 'gizmo', 'doohickey']
@renderer
def widgets(self, request, tag):
for widget in self.widgetData:
yield tag.clone().fillSlots(widgetName=widget)
@renderer
def header(self, request, tag):
return tag('Header.')
@renderer
def footer(self, request, tag):
return tag('Footer.')
def printResult(result):
print result
class Root(Resource):
isLeaf = True
def render_GET(self, request):
request.write("<!DOCTYPE html>\n")
#flattenString(request, Hello()).addCallback(request.write)
flattenString(None, WidgetsElement()).addCallback(request.write)
request.finish()
return NOT_DONE_YET
root = Root()
root.putChild('styles', static.File("styles"))
site = Site(root)
reactor.listenTCP(8080, site)
reactor.run()
So if anyone has some clues as to what I should look for next that would be
very welcome.
